Odd-even dependence of rectifying behavior in carbon chains modified diphenyl-dimethyl molecule

We present a systematic study of the effects of asymmetric nonequi-length carbon chains on the electron transport properties of diphenyl-dimethyl molecule. Significant odd-even dependence is observed: the rectification appears only in the hybrid nanostructure with odd carbon chain on one side and even carbon chain on the other side, while it is negligible in those with odd/even carbon chain on both sides.128
